Definitions
- the invention relates to a vehicle crane - in particular articulated arm crane - with a lifting arm and one or more articulated arms which are mutually variable in geometry and one can be guided or guided on the crane arms load rope.
- the invention relates to a method for keeping constant a voltage of a load part of a vehicle crane.
- the object of the invention is to provide a comparison with the prior art improved vehicle crane.
- the compensation device can be a rope overuse or slack rope formation when unfolding and when folding the crane arms are prevented. Furthermore, during crane operation, the compensation device can carry a substantially load-free rope synchronously with the crane arms pivoting towards one another. This can be achieved in that the compensation device causes a substantially constant and constant tension of the load rope. Further advantageous embodiments of the invention are defined in the dependent claims.
- the compensation device in the change of the geometry of the crane arms the tension of the load rope to a substantially constant and constant value regulates.
- a uniform tension of the load rope can be achieved with any change in the geometry of the crane arms.
- the compensation device is designed hydraulically. Since many mobile cranes already have a hydraulic winch, thus, the compensation device can be included in the existing hydraulics.
- the compensation device has at least one pressure relief valve.
- the compensation device has at least one directional control valve - preferably a 2/2 way valve. It has proven to be particularly advantageous if the at least one directional control valve is designed to be electrically switchable. Thus, a simple way can be achieved to turn the directional control valve off or on.
- the vehicle crane has a winch, wherein the compensation device is at least partially formed on the winch. This achieves a compact design.
- the winch has a drive, wherein the compensation device cooperates with the drive of the winch. Together with the drive of the winch already existing hydraulic training of the winch can be used and influenced by the compensation device.
- the compensation device has a displacement transducer, wherein the displacement transducer is releasably securable at the cable end of the load rope. It has proved to be particularly advantageous if the position transducer has at least one spring element, preferably a gas spring. Spring elements are a particularly cost-effective variant to make changes in length compensated.
- Protection is also desired for a method for maintaining a constant tension of a load rope of a vehicle crane, in particular a articulated crane, wherein the load cable on a lift arm and one or more articulated arms, which are mutually variable in geometry, is guided
- the load rope is stretched by a compensation device by means of a winch
- FIG. 1 is a side view of a articulated crane with compensation device
- Fig. 2 is a schematic circuit diagram
- FIG. 3 shows a variant of a compensation device in a vehicle crane in side view
- Fig. 4 shows a vehicle with a vehicle crane with compensation device in side view.
- FIG. 1 shows the crane arm system 110 of a vehicle crane 100 with a lifting arm 106, articulated thereon, a first articulated arm 101 and on this first Knickarm 101 - which is telescopically formed - a hinged second articulated arm 102nd
- the vehicle crane 100 in this case has a winch 104.
- This winch 104 is used for lifting loads by means of the load cable 103rd
- the cable 103 can remain reeved when folding the crane arm system 110 of the vehicle crane 100.
- the load cable 103 is normally fastened to a fixed point 107 during folding on the second articulated arm 102. Since the load cable 103 extends from the lift arm 106 via the first articulated arm 101 and further from the crane push arms of the first articulated arm 101 to the second articulated arm 102 via a plurality of pivot points, the folding of the articulated arms and the displacement of the crane push arms results in a shortening or lengthening of the cable 103.
- the crane arm system 1 10 of the articulated-arm crane 100 shown in this embodiment can, on the one hand, pivot the two articulated arms 101 and 102 relative to one another such that the two articulated arms 101 and 102 lie substantially parallel to one another in at least one of their two end positions. Likewise, the two crane arms 106 and 101 can be pivoted to each other, that too these are in at least one of its two end positions, the two crane arms 106 and 101 are substantially parallel to each other.
- This articulated crane 100 in this case has a compensation device 1 for tensioning a load cable 103, wherein the compensation device 1 with the winch 104 of the articulated crane 100 cooperates - exactly with the drive 105 (not shown, see Fig. 2) of the winch 104. As from this Figure 1 is apparent, while the compensation device 1 is formed on the winch 104 of the vehicle crane 100.
- FIG. 2 shows a schematic circuit diagram of the winch 104 including supply with a load cable 103 arranged thereon.
- the winch 104 has a drive 105 in this case.
- the compensation device 1 is arranged at this drive 105.
- the drive 105 is controlled via the main control valve 14 of the crane for lifting and lowering the load cable 103 of the cable winch 104.
- the liquid container 13 provides the necessary liquid - preferably oil - for the hydraulic drive 105 available.
- the 2/2-way valve 2 - the 2/2-way valve 2 is electrically switchable 6 is formed - opened and the function "lift winch" is activated on the main control valve 14.
- the resulting pressure opens the brake 11 and the oil flow causes the cable winch 104 to retract and tension the cable 103.
- the winch 104 stops and the oil flow returns via the pressure limiting valve 3.
- the pressure set at the pressure limiting valve 3 gives the height of the cable pulling force.
- the cable 103 is wound further as described above. In this case, the maximum cable speed results from the set on the main control valve 14 oil flow. If an extension of the free end of the rope is necessary, the winch 104 is rotated in the opposite direction by the cable pulling force and the cable 103 is unwound. Due to the constantly applied pressure by the function activated on the main control valve 14 "lift winch" the brake 1 1 always remains open and allows The control of the cable pull force is thereby bypassed by the compensation device 1.
- the tension of the load cable 103 of a vehicle crane 100, not shown, (see FIG. 1) is kept constant, with the load cable 103 being guided on the lift arm 106 and the articulated arms 101 and 102 (see FIG. 1), the load cable 103 passing through in one step the compensation device 100 is tensioned by means of the cable winch 104, in a further step - with a change in the geometry of the crane arms 106, 101 and 102 to each other - which causes a shortening of the guide load of his load cable 103 on the crane arms 106, 101 and 102 - the load cable 103 through the compensating device 1 is wound on the winch 104, however, in a further step - in a further change in the geometry of the crane arms 106, 101, 102 to each other - which causes an extension of the guide of the load cable 103 to the crane arms 106, 101, 102 - Lastseil 103 is unwound by the compensating device 1 of the winch 104.
- FIG. 3 shows a variant of a compensation device 1 on a part of the crane arm system 110 in side view.
- the crane arm system 110 in this case has the two crane arms 101 and 102, a further crane arm 106 is not shown here.
- the compensation device 1 acts on the cable fix point 107 of the cable 103.
- the winch 104 (not shown) is controlled via the position sensor 30 at the cable fix point 107.
- This displacement sensor 30 consists of a spring element 32 - preferably a gas spring - which is retracted in the unactuated state. This setting is via a switch (not shown) supervised. The activation of the compensation device 1 is not possible in this position, since it is the normal winch operation.
- the cable end 31 is attached to the transducer 30 and biased by winding the cable 103 with the winch 104, the spring element 32 about half its stroke.
- the activation of the compensation device 1 is now possible, their release is carried out by the monitoring switch, not shown.
- the position of the spring element 32, actually its stroke, is measured with an analog sensor (not shown) and forwarded as an electrical signal to the controller (not shown) of the winch 104. Via this control, the winch 104 is activated and the cable 103 is either wound up or unwound until the position sensor 30 reaches the middle position.
- FIG. 4 shows a side view of a vehicle 50 on which a vehicle crane 100 is arranged.
- the crane arm system 1 10 of the vehicle crane 100 in this case has the lifting arm 106 and an articulated arm 101.
- the winch 104 is arranged in this preferred embodiment, which has the compensation device 1.
